Ah, to be young again. Being forced to grow up, we missed the whole rave thing. Flash mobs too. But now we're ready to play catch-up big time, with this self-illuminating hair gel. Just mix the gel, apply as directed, and you're good to go for up to 8 hours (which, at our age, is way more time than needed.) You can even enhance your Halloween accoutrements with it. Now we just have to figure out how to get it past airport security.
